Metallurgical applications of deep eutectic solvents (DESs), known as ionometallurgy, have received significant research attention in recent years. While many studies claim that DESs are generally green and enhance process efficiency, others believe industrial ionometallurgy not viable. Here, we report on leaching experiments a sulfide flotation concentrate using ethaline, chloride-based DES, the presence common oxidants. Following mineral-based approach, compare results with those obtained...
Many environmental and industrial processes depend on how fluids displace each other in porous materials. However, the flow dynamics that govern this process are still poorly understood, hampered by lack of methods to measure flows optically opaque, microscopic geometries. We introduce a 4D microvelocimetry method based high-resolution X-ray computed tomography with fast imaging rates (up 4 Hz). use fields during unsteady-state drainage, injecting viscous fluid into rock filter samples. This...
Abstract To safely and efficiently utilize porous reservoirs for underground hydrogen storage (UHS), it is essential to characterize transport properties at multiple scales. In this study, hydrogen/brine multiphase flow 50 bar 25 °C in a 17 cm Berea sandstone rock core was characterized visualized the pore scales using micro X-ray CT. The experiment included single drainage imbibition cycle during which relative permeability hysteresis measured, two no-flow periods study redistribution of...
Encouraged by the need for ecologically and economically sustainable technologies recovery of metals from complex raw materials, ionometallurgical leaching using deep eutectic solvents is emerging as a promising alternative to conventional hydro- pyrometallurgical process routes. Current approaches studying processes do not provide mineral-based understanding – thus limiting opportunities optimization. This study addresses this shortcoming combining laboratory-based X-ray computed tomography...
Permeability plays an important role to determine the characteristics of how fluids flow through a porous medium which can be estimated using various methods. Darcy's law and Kozeny-Carman equation are two most utilized methods in estimating permeability. In law, permeability calculated by applying pressure gradient between opposing sides inlet-outlet certain direction. The then depends on fluid viscosity flowrate. is empirical several parameters such as shape factor pore, tortuosity,...
Mineral dissolution is a dynamic process in which kinetics depend on the reactive surface area, orientation, and geometry of dissolving mineral grain. Dissolution rate is, thus, not represented by single value, but rather, spectrum that affected reactivity different types features. Such spectra are usually obtained very detailed studies perfectly cleaved surfaces atomic force microscopy or situ studies, such as flow-through experiments. This study visualizes progress repeated X-ray computed...
Mineral dissolution is an important process that occurs in both natural as well anthropogenic processes. The kinetics of such processes are influenced not only by the characteristics solution but also minerals, crystal defects on microscopic scale or macroscopic features intersection planes to form edges and corners. Macroscopic known increase population steps kinks may, turn, affect rate over time. Hence, this study presents a 3D empirical model aimed at examining time-series evolution...
This study presents the analysis of crystallization impact in four lime-based mortar mixtures order to determine extent decay during salt crystallization, affected by use additives and change microstructure. For this purpose, non-destructive micro-computed tomography was used monitor lime cores. technique allowed tracking precipitation after accelerated weathering steps further enabled localization damage due both time space. Results indicate that internal 3D microstructure mortars is...
Abstract Interaction between fluids and solid surfaces plays important roles in many fields, e.g.: enhanced oil recovery (EOR), environmental engineering, agriculture, materials, etc. Research on this topic is intensively carried out by researchers. In research, a simple experimental setup for fluid contact angle measurement constructed using an optical microscope video camera with 29 frames per second. Measurement of variation salinity, i.e.: 1M, 2M, 3M, 4M, 5M recording single droplet...
